FLYTRAP.

Application filed December 4, 1922. Serial'No. 604,802.

To all whom t may concern Beit known that I, Louis H. Kohn, Aa citizen of the United States, residing at Casper, in the county of Natrona, State of AWyomin have invented certain new and useful Im] rovements in Flytraps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in traps, and particularly to fly traps.

One object of the invention is to provide a fly trap which may be suspended on a wall, on a window screen, on a screen door, without interfering with the use of the door orv window.

Another object `is to provide a device 'of this character which is simple in eonstruce tion, can be manufactured at a low cost, and which will attract'and effectually trap the flies.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing In the drawing:

Figurel is an elevation of the trap suspended on a window screen.

Figure 2is a vertical longitudinal central sectional view through the trap, on line 2-2 of Figure 1.

Figure 3 is a vertical longitudinal central sectional view on the line 3 3 of Figure 2.

Referring particularly to the accompanying drawing, the frame of the trap consists of two angular yokes 10, `formed from suitably stiff` wire and "disposed in parallel planes, with the lower end portions ofthe arms connected by the cross bars 11. Secured to and extending between cross bars 11 is a narrow trough 12 in which is placed the bait `to attract the flies. Secured to the side of thetrough is a strip of some brilliantly colored material 13, to attract the flies to the trough.

Secured to, and extending around the frame yokes 10, are lthe side and end walls.

14 and 15', which are formed front woven wire fabric of the ordinary mesh used in screen windows and doors. same wire .screen material, 16, is secured to the bight portions of the yokes, toform the upper end wall of the enclosure,.the bottom.

being left open, and with the lower edges of A strip of the the walls 151 and 15 Ispaced a short distance above the trough.

Disposedwithin the enclosure is a pyra-I mid 17 of screen fabric, the same having it lower end open, and with the marginal ed es secured to the walls 14 and 15, while its upper, or' apex end, is provided with a small opening through which the flies enter the enclosure, and are trapped, after crawling upthe inner faees\of the sides of the pyrami In one end portion of the top wall there is formed an opening through which the dead flies are dumped, said opening being closed by a plvoted door 18.

To one of the bight portions there is secured an upwardly extending loop 19 for engagement with a nail or hook, whereby the trap may be suspended .on a wall.

Secured to the sides of theupper end of the trap, and extending rearwardly and downwardly therefrom, are the pointed pins 20, which are adapted to be inserted in the mesh of the screen fabric of a window or door, to support the trap.

V It will be noted' that the strands of the w1re, at the apex opening of the pyramid,

`extend upwardly from the opening, thus door or window-screen without interfering with the opening'and closing of the window sash, or of the house door.

It will be noted that the trough is considerably narrower than the enclosure, and that the lower marginal edges of the walls ofthe enclosure are disposed a short distance above and outwardly of the side edges of the trough.v By this arrangement, and in view of the fact that flies move upwardly and forwardly, at an angle, when. leaving the place of alighting, when the flies leave the trough they are directed upwardly into Ithe pyramid, and when they again alight, it is on the'innen' face of one of the walls of the pyramid, from whence they crawl upwardly and pass out of the apexopening into the trapping chamber.

`What is claimed is:

A ilyA trap comprising angular U-shaped wire members disposed in close parallelv relation, an elongated trough extendinglongitudinally between the lower ends of the legs of said members and transa pair of inverted to the trough, andes'nare within the reticulated enclosure having its lower. end secured to the walls of the enclosure a short distance 10 above the lower edges of the reticulated mnteri'al.
